The sockets 12and-13 include the threaded shells 22 and '23 respectively, which are'cov-' -ered by the internally threaded insulating sleeves 24. a The shell 22 and 23 are held with relation to the body lO'by means of the screw threaded members 25 and" 26",

I Itbeing understood that these con tacts 28281are also suitably insulated from the" shells 22 and 2 3 in the usual manner. These contact elements areheld with relation to the body portion 10 by means of o a threaded member 29 which also has an enlarged'fhead andthe nut'30. This mema ber 29 passes through the body portion 10 i andois'larra-nged parallel to the members a use.

By referring I to Fig. 311; will be seen 'rthat the members 14- and 22 r contact 'withrthe f transverse members such as 29 and 25, and I *that' said members29fandf25 terminate in a connection with the shells 22* and23 and j the i contact elements" 2828,' respectively 'Thus when the plug end '11 is inserted into a socket, "current will flow throughthe' mmberslet and; 29 to the contact elements I 28 28, through the lamps in the'socke'ts l2 7 1 and13, to theshells 22 and-23, through the '10 member 25 to the conductor 22 and thence jiand out over the line. 5 l v Whereas the;1nvent1onj1s illustratedv as -f sockets without demanding that anythingbe done to. the latter, also that the-sockets may beseparated from' thebody portion without ";demanding that the plugend be interfered the 'inventiom'it is obvious thatchanges and H l combination of abody portion,"a plugandr o .agplurality' of sockets 'securedj to it hebo'dya "tiers Patent is":
